Hybrid Airplane Whirligig

thingiverse

This is a hybrid project combining woodworking and 3D printing. I was inspired by this video https://youtu.be/l2514xObN6s I started by drawing out and cutting the wooden parts. I used 3/4" pine for all parts. I then designed and 3D printed the prop assembly. The hub has two bearing housings on each side. These are 608 sealed bearings. The bearings allow for a 5/16 bolts to act as a shaft. I designed and 3D printed the engine cowls with holes that I tapped for 5/16-18 bolts. I also included a template for locating the holes to be drilled in the main wing. I used self-tapping flathead screws with tapered holes in the wing. Don't forget your pilot holes. I designed and 3D printed the tail wingtips. I used self-tapping screws to attach. Don't forget your pilot holes. I hand painted the cockpit, but I designed and cut my own decals for the rest. I used Loctite to secure the bolts in the props. I used 1/2" aluminum rod as the upright support. I drilled a 3" hole and pressed the rod in place. You will need to use a short piece of steel u-channel as support where the aluminum rod is located. There is not much wood left after drilling the 1/2" hole for the rod. I wish I would have used a thicker piece for the body. I used a piece of 1/2" EMT conduit for the upright stand. The only support you need is for the lower bearing housing. I used PLA+ for the filament. A short video can be found here: https://youtu.be/8nMZJkLHSEo
